Rationale: Physician assistants are healthcare providers who are licensed to prescribe medications. They have the legal ability to give telephone orders for medications. Nurse midwives primarily focus on providing prenatal care and assisting during labor and delivery. Physical therapists specialize in rehabilitation services. Pharmacists dispense medications and provide medication counseling. Therefore, among the options provided, physician assistants are the correct choice for giving telephone medication prescriptions.

Correct Answer: D

Rationale: Corrected Rationale: Signs of dehydration include dry mucous membranes and decreased urination, among other symptoms. Bradycardia is not a typical sign of dehydration; instead, tachycardia (increased heart rate) is more commonly associated with dehydration. Therefore, option A is incorrect. While dry mucous membranes and decreased urination are indicative of dehydration, selecting only one of these symptoms would not provide a comprehensive assessment. Hence, option D, which includes both dry mucous membranes and decreased urination, is the correct choice.

Correct Answer: B

Rationale: The correct answer is B: Limit alcohol consumption. When managing hypertension, it is crucial to reduce alcohol intake as it can raise blood pressure. High alcohol consumption can also interfere with the effectiveness of antihypertensive medications. Choices A, C, and D are incorrect. Increasing sodium intake (Choice A) is not recommended for hypertension as it can lead to fluid retention and elevated blood pressure. Eating a high-protein diet (Choice C) or following a high-fat diet (Choice D) are also not ideal for managing hypertension, as they can have negative impacts on cardiovascular health.

Correct Answer: B

Rationale: Correct Answer: Dilute the medication. Potassium chloride should always be diluted before administration to avoid irritation and complications. Choice A is incorrect because administering it as a bolus can lead to adverse effects. Choice C is incorrect as giving it rapidly can be dangerous. Choice D is incorrect as monitoring the respiratory rate is not directly related to administering potassium chloride.

Correct Answer: C

Rationale: The correct answer is C because during a testicular self-examination, it is crucial to note a uniform consistency of the testicles. Any lumps, changes in size, or inconsistencies should be reported to a healthcare provider promptly. Choice A is incorrect because pain is not typically expected during a testicular self-examination. Choice B is incorrect as uniform size and shape are not as relevant as uniform consistency. Choice D is incorrect; testicular cancer usually causes enlargement rather than shrinking of the testicles.
